IPC: F02M25/08
Filed: 1984-01-31
Abstract: PURPOSE:To increase or decrease the fuel purge quantity from a canister corresponding to the intake air quantity and control the enrichment of the intake mixture and reduce CO concentration in the exhaust gas by connecting a purge passage extended from the chanister to an air breed passage in a carburetor. CONSTITUTION:An evarporated fuel from a fuel tank 1 is introduced to a canister 2 through a charge passage 3 and adsorbed to the canister 2. the adsorbed fuel to the canister 2 is purged thereform through a purge passage 4 branched from the purge passage 3. In this construction the purge passage 4 is connected to an air breed passage 6 of a carburetor 5.
